Nettet3. feb. 2024 · Mountain wave clouds gather across Alberta skies. Weather expert Kyle Brittain says the clouds can form when the wind is blowing over the Rocky Mountains and is generating downstream … NettetMountain waves are vertical oscillations of the air as it flows over mountains. They are discussed in much more detail in Learning Goal 3d, and mountain wave clouds (lenticular clouds) are described in Learning Goal 1b. So here we give only a brief overview of mountain waves.
Nettetfect of mountain-wave-induced PSCs (e.g.Fueglistaler et al., 2003;Eckermann et al.,2006;Plougonven et al.,2008;Noel and Pitts,2012), but they need input of a previous simulation of a global model or a reanalysis to provide the boundary conditions (e.g.Weimer et al.,2016). Thus, mountain waves and mountain-wave-induced PSCs … NettetHarmonic rotating mountain wave clouds from Roineabhal, Isle of Harris, Hebrides, Scotland by @eddy_weather
Nettet29. mar. 2024 · You must gaze at a rotor cloud to see its whirl. Rotor clouds are a sign of turbulence in the mountain wave and a pilot must be ready to be tossed about. In my Navion, many times in severe turbulence near rotor clouds, I’ve had to hold on to my seat with both hands and lean away from the canopy post. Another wave cloud is the … NettetLenticular clouds are typically formed when moist air, which is relatively stable, flows in a vertical direction over a mountain. When this vertically moving air comes in contact …
Nettet25. apr. 2012 · Mountain clouds produced by orographic lifting of moist air to saturation. Clouds formed by upslope winds are generally stratiform, those formed by mountain wave updrafts are often lenticularis -type or wave clouds, and those formed by heating, such as elevated heat source or leeside convergence effects, are generally cumuliform.
NettetThe wave length of lee clouds depends on atmospheric stability and wind speed but not on topography. Short wave lengths occur in very stable atmospheric conditions with low wind speeds while high wind speeds and a less stable atmosphere generate longer wave lengths. The relationship between wave length λ [m], wind and stability is given by: glass fibre sheetingNettetNacreous clouds that form in the lower stratosphere sometimes have lenticular shapes.
